LIGHTING SYSTEM


  1. FUNCTION OF MAIN COMPONENTS

    Component Function

    Brake Actuator Assembly


    • Skid Control ECU

    		 Receives various signals and transmits an emergency brake signal to the semiconductor PWR integration ECU.
    Semiconductor PWR Integration ECU Receives an emergency brake signal and flashes the stop lights.
    Speed Sensor Detect the wheel speed of each of the 4 wheels.
    Yawrate Sensor Outputs the acceleration information.
    Stop Light Switch Assembly Detects when the brake pedal is depressed.

  2. SYSTEM CONTROL


    1. The activating and deactivating conditions for the emergency brake signal are as shown in the following table:

      Condition Details

      When all of the following conditions are met, the emergency brake signal starts operating:


      • Vehicle speed is above 55 km/h (35 mph).

      • Driver is depressing the brake pedal.

      • Emergency braking is detected from the vehicle deceleration.
      Emergency Brake Signal Ending Conditions

      When any of the following conditions is met, the emergency brake signal stops operating:
